Astrolux EC01 flashlight review: XHP50.2 LED 3500 LUMENS

Introduction:

Astrolux has come out with many quality and budget flashlights over the past couple of years and every time they come out with a new one it is always something special, and in this case, it’s the EC01. Astrolux claims the EC01 is a compact high output EDC light, and it definitely fits that description. Putting out 3500 lumens as well as having the capabilities of a built-in charging port this light is an excellent option for many people.

What you'll get:

The packaging came intact and came in a cardboard Astrolux branded box. The flashlight comes in bubble wrap which is then wrapped in a foam sheet which prevents it from rattling around in shipping and getting damaged.

Handling of the light

The EC01 fits like a glove in the hand and it is a definite candidate for an EDC flashlight due to the size. It can be carried in the pocket without problems as it also isn’t heavy enough to weigh down your pants. The flashlight feels great in the hand with the cross pattern knurling on the handle giving some grip as well as it being relatively small in diameter. There is a set of heatsink fins on either side of the flashlight head which if touched from a certain angle can feel slightly sharp.

Tail-standing:

  • This flashlight can also tail-stand with ease due to the wide tail cap providing balance.

Build Quality, knurling, threads, and anodization

The build quality is exceptional on this flashlight everything is nice and smooth except for minimal parts of the heatsink. The anodization is providing full coverage and is not scratched or dented from the factory. There is a stainless steel bezel as well as a stainless steel ring around the button that provides a nice contrast with the black body. The button is backlit by 2 green LEDs which is always an appreciated touch on any flashlight, by no means does this feel or look like a cheap flashlight.

The threads on the tail cap are massive, squared off and smooth which is always nice to see on a premium flashlight. The threads on the top half of the body tube which connect the body to the head are not squared off, they are regular pointed threads but are not thin or bad quality. The threads are nice and smooth and do not squeak when removing either end.

LEDs, Lens, Bezel and Reflector

The EC01 uses the CREE XHP50.2 LED, this is a powerful LED that suits this form factor well. It only comes in one tint which is ~6000k, other tints may be available in the future. The reflector sports an orange peel finish, this cuts down beam artifacts and promotes a smoother beam pattern. The glass is thick and very clear but is not AR coated.

The beam pattern is very appealing and smooth, there is a large definitive hotspot with bright spill to fill in the background. The majority of the beam is a cool icy blue color and the only spot that is a bit discolored is the corona around the hotspot which is slightly yellow. There is also a semi crenulated SS bezel.

Lock-out mode:

PWM:

Upon testing and research, this light has PWM on all ramped modes except Turbo.

Batteries and charging:

The EC01 takes a 21700 cell, it can accept flat-top cells but not protected cells as they are too wide for the body tube as well as too long for it to close without crushing the battery. The manufacturer includes a 18650 sleeve if you wanted to use those you could as well. There is a USB-C port included on the side of this light that can be used to charge a battery that is inserted in the light, the button will glow red when charging and green when complete (port charges at a very fast 2A charge rate!).

It's a great rechargeable flashlight, for sure.

Performance:

Amp measurement:

No definitive modes so I chose spread out spots on ramp to measure:

  • Moon: 0.01A
  • Low(~100lm): 0.17A
  • Med(~600lm): 0.78A
  • High(~1900lm): 3.3A
  • Turbo(~3400lm): 14.8A (with Samsung 21700 40T)

Runtime graph

The Astrolux EC01 has a predictable runtime with it starting to drop off from turbo after about 10 seconds all the way down to ~800 lumens and bounces around from there up to 1000 and down to 600 back and forth after it finally dying after 140 minutes with a 4000mAh Samsung 21700 40T.

Astrolux EC01 Lumen measurements (for each mode)

I used a homemade lumen tube design that many people use, it is made from 3 - 3” PVC Street 90s and a cap with a hole drilled in it to hold the DR Meter LX1330B which I bought on amazon.

  • Moon: 1 lumen
  • Low: 112 lumens
  • Med: 632 lumens
  • High: 1889 lumens
  • Turbo: 3478 lumens

Throw numbers:

The factory claims 298m of throw, after measuring from 5m with the Dr Meter LX1330B I got a total of 31,500cd @1m and 355m of throw which is roughly 16% more output than the factory claims.

Overall Rating: very good

Overall I like this flashlight a lot, it has lots of good features that many people look for such as lightweight, small size and high brightness. The tint could be better but there is now a 5000k version available which Id say would be a better choice for EDC purposes. I give this light a 4 out of 5 stars for its good features and overall feel compared to other lights of this caliber.
